该句中包含有三个定语从句。When the killer whales, or “killers” as they were then called , helped the whalers catch the baleen whales 是关系副词when引导的定语从句，修饰先行词a time；as they were then called是关系代词as引导的定语从句，意为“正如当时被叫做的”，修饰先行词“killers”；that were on their annual migration 是关系代词that引导的定语从句。

[练习] 汉译英

2. On the afternoon I arrived at the station, as I was sorting out my accommodation, I heard a loud noise coming from the bay.

本句为主从复合句，主句是I heard a loud noise coming from the bay；I arrived at the station为省略了关系词that 的定语从句；as在句中引导时间状语从句。

developing countries 定语working people 定语

StepIII师导生学，互动探究（师生互动）

一、V-ing被动形式的构成（group work 师导生学合作探究）

【观察探究】

V-ing 一般时和一般时的被动形式;

1）He hurried home , looking behind from time to time .

2) The building being repaired is our dormitory .

V-ing 的完成时和完成时的被动形式

1) Having lit a candle , she went out.

2) Having been asked to stay , I couldn’t leave .

3) Having heard this , our teacher expressed her satisfaction .

【归纳总结】

如果v-ing与句中的逻辑主语构成被动关系，即当动词-ing 形式的逻辑主语是动作的承受者

时，需用其被动形式（being done，having been done）。

其否定形式是：not being done, not having been done

V-ing 形式表示的动作与主句谓语动词同时发生，用其一般式; V-ing 形式表示的动作在主句谓语动词之前发生，用其完成时。

【即学即练】

人们不喜欢无缘无故的赞扬。People hate being praised for nothing .

这问题远没得到解决。The problem is far from being solved .

她不介意被一人留在家里。She didn't mind being left alone at home .

没有被邀请参加聚会，他感到很不高兴。

He was unhappy for not having been invited to the party.

尽管被告诉好多次了，但他仍然犯同样的错误。

Having been told many times, he still made the same mistakes.

二、v-ing被动形式的语法功能（互动交流，突破疑难）

1.作主语

Swimming is good for health.

___________ (raise) your hat to a a lady is good manners . 对一位女士脱帽致敬是礼貌的。

★ ____________ (kill) by sharks in the sea is a common thing .

2. 作表语(往往表示一种概念，习惯或经验，或说明主语的内容.)

Teaching is learning 教学相长．

My hobby is __________ (make) model planes.

☆ Her regret is______________ (abandon) by him.

注意

1). V-ing形式和不定式都要有对称性To see is to believe.= Seeing is believing.

2).动名词和不定式都可以作主语，动名词作主语表示一般或抽象的多次性行为，不定式作主语往往表示具体的或一次性的动作。如：

Playing with fire is dangerous. （泛指玩火）

To play with fire will be dangerous.（指一具体动作）

3.作宾语

We would appreciate hearing from you．我们会珍惜你的来信。

★ The bird escaped ______________ (catch) .

★ He was afraid of ____________ (abandon) by us.

V-ing 形式既可作动词的宾语, 也可作介词的宾语。

注意：

在avoid, admit, appreciate, consider, delay, enjoy, escape, excuse, finish, forgive, imagine, mind, miss, practise, risk, suggest, give up, put off, feel like, insist on , instead of, look forward to, object to, keep on等后只接V-ing形式作宾语。
